Lock nut

Lock nut (also known as anti-loosening nut) is a special nut with anti-loosening structure. Nylon lock nut (nylon insert type): the inner hole of the nut is inlaid with a nylon ring. When tightening, the nylon ring squeezes the bolt thread to prevent loosening. It is the most commonly used and moderately cost. Metal lock nut (metal insert type): embedded with metal elastic piece or locking ring, relying on metal elastic deformation to lock, high temperature resistance and wear resistance.

Surface treatment: galvanized, blackened, phosphated, hot-dip galvanized

Specifications: M3-M36, #4-40 to 1/2"-13

Main uses

Automobiles and construction machinery: used in automobile chassis, engine brackets, excavator hydraulic components, 8 High-strength models above grade are resistant to bumping and vibration, and are key safety components.

Machinery and equipment manufacturing: used in motors, pump valves, machine tools, and conveyors to adapt to high-speed operation or high-frequency vibration conditions to prevent equipment failure caused by loose nuts.

Construction and transportation: used in steel structures, scaffolding, bridge supports, and rail transit components. Hot-dip galvanized models are corrosion-resistant and anti-loosening. Ensure structural safety.

Military industry and special equipment: used in military machinery, aerospace accessories, and ship power systems. The metal anti-loosening structure is resistant to harsh environments (high temperature, low temperature, salt spray), has strong anti-loosening reliability, and is suitable for extreme working conditions.

Electronic and general scenarios: used in home appliances, instruments, and outdoor facilities. The nylon version is suitable for light equipment, and the stainless steel version is suitable for wet conditions. / Corrosive environment, easy to maintain.
